ABSTRACT
Laundry business is currently growing rapidly so that it has the potential to pollute the environment because the wastewater produced is often discharged into water bodies without being treated first. One of the waste treatment that can be used in the laundry business especially in Bali is the constructed wetland wastewater treatment system. In this research, it is known the effectiveness of the Vertical Flow Subsurface Flow Constructed Wetland wastewater treatment model using kintamani volcanic rock and wood charcoal filter media, and using lemongrass plants (Cymbopogon citratus) in treating laundry wastewater measured by the parameters of Total Phosphate and Ammonia. The results showed the effectiveness of the Total Phosphate and Ammonia reduction system for 5 weeks in each reactor, namely; reactor 1 (50% volcanic rock, 50% charcoal) by 26.69%, reactor 2 (75% volcanic rock, 25% charcoal) by 37.32%, reactor 3 (25% volcanic rock, 75% char) by 20 , 94%, reactor 4 (100% volcanic rock) by 26.91%, reactor 5 (100% charcoal) by 55.17%. Based on the results of the study, the constructed wetland reactor system used in this study is not yet effective in treating laundry wastewater, if applied to other laundry it will produce lower performance because the value of the wastewater parameters in other laundry can be significantly higher compared to laundry in this study.
